Produce lines of reproducible test fixture by repeated hashing.
For a given set of options the output is deterministic, it will always have the same checksum. So a large file can be reliably generated on demand, rather than downloaded or stored in version control. Conversely the expected checksum can be checked into version control, e.g. as part of a test suite.
Usage
>>> import hash_fixture
>>> lines = list(hash_fixture.lines(line_count=3))
>>> for line in lines: print(line)
